Welcome to the Gartenwasser wiki!

This project aims to build a smart sprinkler controller.

Four magnetic valves with attached hall-sensor-flow meters are connected to a 4 channel Relais card controlled by a raspberry pi A+. A LCD keypad module shows the current status and lets the user switch the valves manually on key press. See the complete parts list.

Over WLAN the unit is controllable via the mosquitto MQTT broker that's running on the device itself.

For most of the current home automation solutions, mqtt plugins are available so every of these solutions should be able to integrate the device.

To get things running, the two init-scripts in /init.d have to be placed to /etc/init.d and chmod 755 and sudo insserv'ed.

The hoses were simply connected by standard hose connectors:

I can control the unit with several devices, including my smartphone using SmartVISU:
